Convince me to put a TKX in my Dart

Looks like you've convinced me! I was on the fence about T-56 vs TXK but seeing how you didn't have to hack out the entire middle of the floorpan and fab a new one made the decision for me. The floors in my '70 Duster are mint and I like not having a giant hump in the middle.

I did some soul searching after seeing this install.

Best I can tell the TKX should feel pretty similar to a 2.66 first A833 up to 4th, but with the advantage of an extra gear dropping high way RPM's by about 700. First is deeper on the TKX, but overall I bet it feels about the same.

The thing is, the TR6060 adds another gear and saves about 1200 RPM over the A833 on the highway and probably feels stronger in every gear.

For someone that is mostly running around town and only does limited or moderate highway miles, the TKX seems like a perfect swap. Add that based on this thread the install seems easier, pretty much a win-win for most. The OP talked about this and I suspect that for him it was exactly the right choice.

For me, the TKX puts my highway RPM's within 60 RPM of my current setup. While the better gear spread with 4 gears below OD versus 3 would make it much more enjoyable around town, I spend too much time on the highway and want to road trip my Duster so I want an even lower cruise RPM than the TKX will give me. For that reason alone I am going to stick to my original plan of swapping a TR6060 into my car when I do the GenIII swap.
